we use the Elecard Codec Packs to create a kind of video conference system. After successfull test in our local network, we want to try the bidirectional streaming via WAN and Internet. Although we have a fixed IP and made the setting for port forwarding, we have still problems by connecting to the stream. Is there any guide how to setup an internet stream with the Codec Pack?

thanks for your answer. I understood that there is just one UDP port used to receive and one to send data and that they are both listed in Ressource Monitor.Let me explain our main problem:

I have two Computers (PC1 /PC2). PC1 listens on Port 21010 to receive an RTP Stream sent by PC2. PC2 listens on Port 22010 to receive the Stream sent by PC1. So I have two streams to create a bidirectional video conference.

Now I want to setup the system to work not only in the local network (via local IPs) but the internet via our external IP. So we set up the routers and the firewall to forward UDP port 21010 to PC1 and port 22010 to PC2. The SDP data is transferred from PC1 to PC2 over a TCP connection. Until this point everything works. PC2 (for example) receives the SDP data from PC1, sets the data to NWSourcePlus and tries to connect to the stream sent by PC1. The connection try times out and the stream couldn't be received.

I don't know how to set the URL configuration, can you please explain it? I tried to connect to the stream of my application with NwPlayer sample application by setting the URL parameters. That doesn't even work in local network.
